Phases of the Moon
What can you see
in the sky during
night time?
What is the
shape of the
moon?
The shape of the moon is round.
However, its shape seems to
change from time to time. There
are times the moon looks round
as a plate. Sometimes it appears
like a banca/boat. These
apparent changes in the moon’s
shape are called phases.
Let us look at
this illustration of
the Phases of the
Moon.
What did you observe?
The moon is a familiar object in
the night sky. It is the only satellite
of the Earth. A satellite is an object
in space that revolves around a
planet. The moon as the Earth’s
natural satellite makes a complete
rotation in one complete revolution
around the Earth in 29 ½ days.
The moon does not produce its own
light. It only reflects the light coming
from the sun. It appears differently at
different times because the
illuminated portion on the moon
changes as it revolves around the
Earth. The apparent change in its
appearance is known as the phases
of the moon.
Let us watch this video
presentation.
Listen carefully and
take down notes the
important details.
